Superlattices of covalently cross-linked 2D materials for the hydrogen evolution reaction

APL Materials, 2020
Amongst the recent developments in 2D materials, van der Waals heterostructures formed by depositing a monolayer or few-layers of a 2D material on a monolayer or on few-layers of the same or another 2D material have attracted great attention.

Passivating the sulfur vacancy in monolayer MoS2

APL Materials, 2018
Various methods to passivate the sulfur vacancy in 2D MoS2 are modeled using density functional theory (DFT) to understand the passivation mechanism at an atomic scale. First, the organic super acid, bis(trifluoromethane)sulfonimide (TFSI) is a strong protonating agent, and it is experimentally found to greatly increase the photoluminescence efficiency.

Carrier and Polarization Dynamics in Monolayer MoS2

, 2014
International audienceIn monolayer MoS2, optical transitions across the direct band gap are governed by chiral selection rules, allowing optical valley initialization.

Epitaxial Monolayer MoS2 on Mica with Novel Photoluminescence

, 2013
Molybdenum disulfide (MoS2) is back in the spotlight because of the indirect-to-direct bandgap tunability and valley related physics emerging in the monolayer regime.

Second harmonic microscopy of monolayer MoS2

, 2013
We show that the lack of inversion symmetry in monolayer MoS2 allows strong optical second harmonic generation. The second harmonic of an 810-nm pulse is generated in a mechanically exfoliated monolayer, with a nonlinear susceptibility on the order of 10−

Giant two-photon absorption in monolayer MoS2

, 2015
Strong two-photon absorption (TPA) in monolayer MoS2 is demonstrated in contrast to saturable absorption (SA) in multilayer MoS2 under the excitation of femtosecond laser pulses in the near-infrared region.

Surface oxidation energetics and kinetics on MoS2 monolayer [PDF]

, 2015
In this work, surface oxidation of monolayer MoS2 (one of the representative semiconductors in transition-metal dichalcogenides) has been investigated using density functional theory method. Oxygen interaction with MoS2 shows that, thermodynamically, the

Broadband Absorption Engineering to Enhance Light Absorption in Monolayer MoS2

, 2016
Here we take a first step toward tackling the challenge of incomplete optical absorption in monolayers of transition metal dichalcogenides for conversion of photon energy, including solar, into other forms of energy.

Atomistic full-band simulations of monolayer MoS2 transistors [PDF]

, 2013
We study the transport properties of deeply scaled monolayer MoS2 n-channel metal-oxide-semiconductor field effect transistors (MOSFETs), using full-band ballistic quantum transport simulations, with an atomistic tight-binding Hamiltonian obtained from ...
